Iranitalab, Amirfarrokh, et Aemal Khattak. « Train-Level and Car-Level Modeling of Hazardous Materials Release in Railroad Incidents ». Transportation Research Record : Journal of the Transportation Research Board 2672, no 9 (6 octobre 2018) : 249–60. http://dx.doi.org/10.1177/0361198118801337.
Texte intégralRésumé :
This paper quantifies the impacts of incident, railroad, environment. and train/car characteristics on the probability of hazardous material (hazmat) release in a hazmat-carrying train incident and provides a prediction tool for hazmat release. Two sets of models utilized the Federal Railroad Administration 2012–2016 rail equipment incident dataset. The units of analyses for these two sets were trains and hazmat cars. Binary logit and binary mixed logit models were investigated to account for hazmat release and potential single-level and two-level grouping in the data (owing to possible hazmat release interdependence among hazmat cars belonging to a train and trains belonging to an incident). Development of receiver operating characteristics curves improved the prediction performance of the models by defining an appropriate cutoff point. Results showed that derailment increased hazmat release probability more than other incident types. Incidents resulting from signal and communication causes were most likely to result in hazmat release. Higher proportion of damaged/derailed hazmat cars and proportion of hazmat cars in a train, track classes 2 and 3, higher train speed, and train gross tonnage were the other important factors. Results of mixed models showed hazmat release from cars belonging to a train were interdependent and hazmat release from trains belonging to an incident were independent. Although models at both levels led to useful results, car-level models had better prediction performance.

Texte intégralRésumé :
Introduction:Ambulances with physicians, known as Doctor Car, and Tokyo DMAT are the two prehospital care systems responsible for medical team dispatch in the Tokyo area. While there are 25 designated hospitals for DMAT, Doctor Car is only available at four hospitals. Our hospital incorporates both systems. While the prehospital care system must be utilized at the time of disaster, Doctor Car was dispatched 418 times in 2017, and the use of DMAT is less than ten times per year.Aim:To review the past disaster responses of our hospital.Methods:The study reviews three cases where our hospital responded to mass casualty incidents and disasters with either Doctor Car or DMAT. The first case was the treatment of crush syndrome caused by a collapsed parking slope. It took more than 24 hours for the rescue, in which the team treated patients during transport and at the hospital. The second case was our response to a mass stabbing incident committed at a facility for the disabled. In collaboration with the onsite rescue team, we conducted triage, hemostasis, transfusion, etc. The third case was caused by a fire in a building under construction. We provided treatments like triage and tracheal intubation on the spot.Results:Because paramedics are allowed to conduct only a limited amount of treatments, dispatch of the medical team to the site is effective.Discussion:For a medical team to be effective at the dispatched site, the team must be accustomed not only to the specific need of medical care during disasters but also prehospital medical care, which may include the abilities to ensure safety during transport and on-site and adapt to the prehospital environment. Doctor Car is a useful way to realize such abilities.

Houbraken, Maarten, Steven Logghe, Marco Schreuder, Pieter Audenaert, Didier Colle et Mario Pickavet. « Automated Incident Detection Using Real-Time Floating Car Data ». Journal of Advanced Transportation 2017 (2017) : 1–13. http://dx.doi.org/10.1155/2017/8241545.
Texte intégralRésumé :
The aim of this paper is to demonstrate the feasibility of a live Automated Incident Detection (AID) system using only Floating Car Data (FCD) in one of the first large-scale FCD AID field trials. AID systems detect traffic events and alert upcoming drivers to improve traffic safety without human monitoring. These automated systems traditionally rely on traffic monitoring sensors embedded in the road. FCD allows for finer spatial granularity of traffic monitoring. However, low penetration rates of FCD probe vehicles and the data latency have historically hindered FCD AID deployment. We use a live country-wide FCD system monitoring an estimated 5.93% of all vehicles. An FCD AID system is presented and compared to the installed AID system (using loop sensor data) on 2 different highways in Netherlands. Our results show the FCD AID can adequately monitor changing traffic conditions and follow the AID benchmark. The presented FCD AID is integrated with the road operator systems as part of an innovation project, making this, to the best of our knowledge, the first full chain technical feasibility trial of an FCD-only AID system. Additionally, FCD allows for AID on roads without installed sensors, allowing road safety improvements at low cost.

Texte intégralRésumé :
For modeling the energy generation of three-dimensional car roof photovoltaic (PV) panels, it is essential to define a scientifically accurate method to model the amount of solar irradiance received by the panel. Additionally, the average annual irradiance incident on car roofs must be evaluated, because the PV module is often shaded during driving and when parked. The curve-correction factor, which is a unique value depending on the three-dimensional curved shape of the PV module, is defined in this paper. The curve-correction factor was calculated using a ray-trace simulator. It was found that the shape of the curved surface affected the curve-correction factor. The ratio of the projection area to the curved surface area of most car roofs is 0.85–0.95, and the annual curve-correction factor lies between 0.70 and 0.90. The annual irradiance incident on car roofs was evaluated using a mobile multipyranometer array system for one year (September 2017–August 2018). It is estimated that the effective annual solar radiation for curved PV modules is 2.53–3.52 kWh m−2/day.

Texte intégralRésumé :
Microblogs are increasingly gaining attention as an important information source in emergency management. In this case, state-of-the-art has shown that many valuable situational information is shared by citizens and official sources. However, current approaches focus on information shared during large scale incidents, with high amount of publicly available information. In contrast, in this paper, we conduct two studies on every day small scale incidents. First, we propose the first machine learning algorithm to detect three different types of small scale incidents with a precision of 82.2% and 82% recall. Second, we manually classify users contributing situational information about small scale incidents and show that a variety of individual users publish incident related information. Furthermore, we show that those users are reporting faster than official sources

Texte intégralRésumé :
The increase in traffic flows on the roads causes an increase in road accidents. The study of the road safety deals on how to reduce the related phenomenon to non-pathological levels; to be able to operate correctly, much different information are needed. For some different levels of investigation of the phenomenon, only the incidental statistics may be necessary. To plan the interventions it needs information on the single incidents that occur in some areas. Each incident has some evolution characteristics that are repeated in a non-random manner, and these recurrences must be highlighted and studied to obtain effective countermeasures. The study methodologies of the road accidents maybe not only on their typology and imply the possibility of reconstruction, even if approximate, of the incident and its temporal phases of development. In some cases, it may also be necessary to evaluate the impact speed between vehicles. Some incident reconstruction techniques allow obtaining reliable speed values before the impact starting from the evidence left on the roadway. If these are not present, it is possible to use methodologies that provide speed values starting from the deformations of the vehicles as a relationship to the structural stiffness coefficients. Some databases are available: these concerning the coefficients obtained for a number of passenger cars and others concerning sister cars: these are used with a reasonable degree of approximation in forensic engineering works. A road safety engineer may not need values with a high degree of approximation but may wish to proceed more quickly with some stiffness coefficients that are not exactly those of a single model of car but only for those of car that has similar characteristics, not equal, with the full advantage of the speed of accident reconstruction. In research work, different stiffness coefficients for passenger cars were analysed and grouped for displacement classes, length and pitch.

Texte intégralRésumé :
Background Improving the design of technology relies in part, on the reporting of performance failures in existing devices. Healthcare has low levels of formal reporting of performance and failure of medical equipment. This paper examines methods of reporting in the car industry and healthcare and aims to understand differences and identify opportunities for improvement within healthcare. Methods A literature search was carried out in Pubmed, Medline, Embase, Engineering Village, Scopus. NHS England and MHRA publications and guidelines were also reviewed. Focus was placed on the current system of reporting in both industries, known degree of patient harm, initiating factors, barriers, quality and methods of incident investigation and their validity. The findings were used to compare error reporting system in the two industries. Results Derivation of healthcare incident data from different sources means the full extent of patient harm is not known. For example, in 2012 there were 13,549 and 38,395 incidents reported by MHRA and NRLS (National Reporting and Learning System) respectively leading to uncertainties on the extent of the problem. The car industry emphasises the role of reporting source in ensuring data quality. Utilising some aspects of this approach might benefit healthcare reporting. These include a specific reporting system that stresses the importance of organisational learning in improving safety and recognises the limitations of root cause analysis. Conclusions Learning from reporting systems within the car industry may help the healthcare sector improve its own reporting, aiding healthcare performance.

Texte intégralRésumé :
Earthquake disasters usually cause panic in the community affected areas, so it is necessary to be analyzed to deal with earthquake events in the future. This paper analyzes data from 9 major earthquakes in Indonesia over the past 4 years and determines 14 critical events. The analysis is based on credible association rules (CAR), data mining, and the maximum clique algorithm. To verify the accuracy of the association relationship and CAR effectiveness, it is performed using a maximum clique algorithm. Based on the results of data mining, that earthquakes have a credible association relationship and have a probability of critical events in various regions in Indonesia. Thus, these results can be used for prediction, early warning, and logistic distribution planning.

On the base of the characteristic analysis in the process with the car crash into guardrail in our country, the paper major in analysis for contact stress and damage of steel concrete, car is solid model and guardrail is elastic-plastic model. Through ABAQUS element software, the paper simulate the dynamic response to the car crash into Reinforced concrete guardrail with different angles and velocities. The incident Angle unchanged, with greater speed is produced the bigger contact stress, in a very short period of time to a peak and quickly decreases. At the same speed, Angle increases, at the same time the damaged region increased. The results show that use the element ABAQUS software to simulate Car guardrail collision is feasible and the speed of cars and collision Angle have greatly influenced the safety performance of the cars and guardrails.

Texte intégralRésumé :
This paper presents a spatial analysis of the association between industrial benzene emissions and the 10-year incidence rates of cancers likely to be associated with benzene exposure (Lymphohematopoietic, lung and lip cancers) at the county level in Texas. The spatial distribution of incident cases of the above cancers between 2004 and 2013 was assessed at the county level and found to have positive spatial auto-correlation. Subsequently, point pattern analysis was performed on industrial emissions of benzene reported to the Toxic Release Inventory (TRI), revealing a non-random spatial pattern. Universal kriging was performed using the industrial emissions data to derive estimates of ambient benzene levels at the county level. An ordinary linear regression model was fitted using the incidence rates as the outcome and the estimated benzene level along with chosen covariates and the residuals were assessed for lingering spatial auto-correlation. As the residuals showed that spatial auto-correlation persists, a spatial conditional auto-regression (CAR) model was fitted instead. In the spatial CAR linear regression model, estimated levels of ambient benzene were not found to be significantly associated with the 10-year incidence rates of lymphohematopoietic, lung and lip cancers at the county level.

Blood 136, Supplement 1 (5 novembre 2020) : 38–39. http://dx.doi.org/10.1182/blood-2020-138737.
Texte intégralRésumé :
Background Today, even though most patients with diffuse large B-cell lymphoma (DLBCL) can be cured with standard immunochemotherapy, 20-30% are refractory to primary therapy or relapse during follow-up with a drastic worsening of the prognosis. In recent years, new promising treatment options including CAR-T cell therapy are becoming available for relapsed/refractory (R/R) DLBCL patients although so far with logistic challenges including disease control and toxicities, and a considerable cost. In view of these challenges, we aimed to estimate the proportion of patients with R/R DLBCL that are likely to be eligible for CAR-T cell therapy in clinical routine, and their expected outcome in the pre-CAR-T era. Methods All patients with DLBCL starting primary therapy with curative intent were identified in the Swedish Lymphoma Register for the period 2007-2014 (N=3550). Primary CNS and primary mediastinal B-cell lymphomas were excluded. Data regarding primary treatment response and relapse was validated through medical chart review in the entire cohort during follow-up until Dec 31st 2017, and information about additional treatment lines including disease characteristics, blood test results, and relapse treatment response was collected. Eligibility for CAR-T cell therapy was estimated retrospectively based on eligibility criteria specified in clinical trials, both at first relapse by applying similar criteria as in the ongoing TRANSFORM, ZUMA-7 or PILOT studies (hereafter termed "CAR-T-2ndline"), and at second relapse applying criteria similar to those specified in the JULIET trial (hereafter termed "CAR-T-3rdline"). Administration of second- and third-line therapies and corresponding response rates were considered as proxies for eligibility and response to bridging therapies. Criteria applied for "CAR-T-2ndline" included R/R DLBCL within 12 months of evaluation date of primary treatment, age 18-75 years, ECOG 0-1, and additional criteria as specified in the TRANSFORM trial (see figure footnote). Criteria applied for "CAR-T-3rdline" included relapse following second-line therapy, age 18-76 years, ECOG 0-1, and additional criteria as in the JULIET trial (see figure footnote). Individuals with missing data on performance status were assumed ineligible. We lacked information about other malignancies in the disease history. Overall survival probabilities were estimated with the Kaplan-Meier method among all R/R DLBCL patients in the trial-specified age intervals and separately among those fulfilling all trial criteria. Results In the cohort of 3550 curatively treated DLBCL patients, 847 (cumulative incidence 23%) experienced R/R disease during a median follow-up of 4.3 years. Median age at first relapse was 71 years (range 18-95 years). Overall, 308 patients ≤75 years experienced progression/relapse within 12 months and were able to start second-line therapy. Of these, 148 patients (17% of all R/R DLBCL patients) fulfilled trial eligibility criteria for "CAR-T-2ndline", of whom 60 responded with at least partial remission (overall response rate, ORR, 41%). At second relapse, 370 patients 76 years or younger received third-line therapy, of whom 55 (6.5% of all R/R DLBCL patients) were deemed eligible for "Car-T-3rdline", and 13 responded (ORR 24%, another 5 patients had SD). Two-year overall survival (OS) among all R/R DLBCL patients ≤75 years receiving second-line therapy was 20% (95% confidence interval, CI, 16-25%) (Fig 1). Among those eligible for "CAR-T-2ndline", 2-year OS was 24% (95% CI 17-31%). Among patients ≤76 years at second relapse, 2-year OS was 18% (95% CI 13-24%), and among those eligible for "CAR-T-3rdline", 21% (95% CI 11-32%). Conclusion In the population-based setting, one in six patients (17%) with R/R DLBCL fitted trial eligibility criteria for CAR-T-cell therapy at first relapse and only one in fifteen patients (6.5%) fitted trial criteria at second relapse at retrospective evaluation. Figures were reduced when adding requirement of response to relapse/bridging therapy. These estimates illustrate to what extent current CAR-T cell therapies may be applied in a routine setting when based on trial criteria, and the need for development of modified and additional therapies in this group. Outcome estimation confirmed a poor outcome in these groups and did not indicate that fulfillment of trial criteria led to selection bias in terms of survival.

Texte intégralRésumé :
In this study, road traffic injury (RTI) was defined as any injury resulting from a road traffic accident irrespective of severity and outcome. Road traffic accident (RTA) was defined as any crash on the road involving at least one moving vehicle, irrespective of it resulting in an injury. This could include collision with a vehicle or any non`moving object while driving/riding a vehicle, collision with a moving vehicle while walking/running/standing/ sitting on the road, or fall from a moving vehicle. The burden of road traffic accidents (RTA) is a leading cause of all trauma admissions in hospitals worldwide. Road traffic injuries cause considerable economic losses to victims, their families, and to nations as a whole. These losses arise from the cost of treatment (including rehabilitation and incident investigation) as well as reduced/lost productivity (e.g. in wages) for those killed or disabled by their injuries and for family members who need to take time off work (or school) to care for the injured. Road traffic fatality in the Kingdom of Saudi Arabia (KSA) is the highest, accounts for 4.7% of all mortalities. Road injuries also are reported to be the most serious in this country, with an accident to injury ratio of 8:6. In this study, we try to focus on some causes of the accidents in KSA, so we can implement the prevention plan.

ObjectiveTo investigate the associations between using alternatives to the car which are more active for commuting and non-commuting purposes, and morbidity and mortality.MethodsWe conducted a prospective study using data from 3 58 799 participants, aged 37–73 years, from UK Biobank. Commute and non-commute travel were assessed at baseline in 2006–2010. We classified participants according to whether they relied exclusively on the car or used alternative modes of transport that were more active at least some of the time. The main outcome measures were incident cardiovascular disease (CVD) and cancer, and CVD, cancer and all-cause mortality. We excluded events in the first 2 years and conducted analyses separately for those who regularly commuted and those who did not.ResultsIn maximally adjusted models, regular commuters with more active patterns of travel on the commute had a lower risk of incident (HR 0.89, 95% CI 0.79 to 1.00) and fatal (HR 0.70, 95% CI 0.51 to 0.95) CVD. Those regular commuters who also had more active patterns of non-commute travel had an even lower risk of fatal CVD (HR 0.57, 95% CI 0.39 to 0.85). Among those who were not regular commuters, more active patterns of travel were associated with a lower risk of all-cause mortality (HR 0.92, 95% CI 0.86 to 0.99).ConclusionsMore active patterns of travel were associated with a reduced risk of incident and fatal CVD and all-cause mortality in adults. This is an important message for clinicians advising people about how to be physically active and reduce their risk of disease.

The perceptual phenomenon of “inattentional blindness” has been widely acknowledged in the scientific literature for 30 years. In addition to the laboratory-based examples, real-life examples appear in the literature. This paper provides a case study where a deputy sheriff’s patrol car collided with a fleeing motorcyclist – with unique circumstances – as recorded on in-car-camera (ICC) videos. Although the motorcyclist brought suit alleging the deputy intentionally collided with him, the deputy reported that he first noticed another deputy running after the motorcyclist prior to seeing the fleeing motorcyclist. However, the ICC video from the involved deputy’s patrol car strongly supports the motorcyclist was visible from the deputy’s perspective before the on-foot deputy appeared. The facts of this incident are compared to the widely accepted characteristics of inattentional blindness in exploring whether that perceptual phenomenon may have been at play in this case.

Texte intégralRésumé :
Abstract Cases of children died in vehicle have been increased each year. Such incident sometimes may happen incidentally especially when children are seated at the rear seats and the problem occurs due to lacking of existing system in detecting children image in a car. Consequently, this study aims to detect the existence of "in-car-abandoned children" using deep learning algorithm. A set of children images model will be classified into two (2) classes; children and no-children via Convolutional Neural Network (CNN) classifier by integrating with programming language, namely TensorFlow. Interestingly, the proposed method can automatically learn pattern features and reduce the incompleteness caused by artificial design features. As a result, a model of sensor that can detect the whole children’s body in various poses with automatic tagging to the children’s image is designed. Accordingly, this study can assist to improve current vehicle systems and create awareness among parents regarding the importance of children’s safety.

Texte intégralRésumé :
Background: Recently, the first asthma-specific Job Exposure Matrix (JEM) was updated to occupational asthma-specific JEM (OAsJEM). Our study aimed to evaluate the association between continued exposure to isocyanates and incident work-related chest symptoms in former car-painting apprentices and to compare the associations using the first and new OAsJEMs.Methods: We used data from an inception cohort of male car-painting apprentices. Post-apprenticeship exposure to isocyanate during follow-up was evaluated using the first asthma-specific JEM (“exposed”=1 or “not exposed”=0) and the new OAsJEM (high=2, medium=1, and none=0). Association between occupation exposure to isocyanate and incidence of work-related rhinoconjunctival and chest symptoms were evaluated through cox regression models, adjusted for age, smoking, wheezing, and non-specific bronchial hyperresponsiveness. Results: The agreement between the two JEMs (exposed vs non-exposed to isocyanate) was perfect (kappa coefficient=0.946, p<0.001). There were only five subjects who were classified as non-exposed based on the first JEM, but had a medium exposure to isocyanate based on the new OAsJEM. Exposure to isocyanate increased the risk of occupational chest symptoms in the high-exposure category (hazard ratio [HR] 2.7, 95% CI 1.1 – 6.6) and the medium category (HR 2.9, 95% CI 0.3 – 30.0) compared to the reference group based on the new OAsJEM, whereas an HR of 2.5 (95% CI 1.0-6.2) was observed from the first JEM. Both JEMs yielded an inconclusive association between exposure to isocyanates and the risk for work-related rhino-conjunctivitis. Conclusion: The asthma-specific JEM and OAsJEM consistently showed that isocyanate exposure increased the risk of incident work-related chest symptoms.

Texte intégralRésumé :
The performance metric for tank cars and other hazardous materials vehicles involved in accidents has generally been conditional probability of release given involvement in an accident. This metric considers the probability of a release event occurring but does not take into account the quantity of product lost in a release incident. In this paper, a new metric termed “release risk” is introduced; it is defined as the expected value of the quantity lost from a tank car given that it is in an accident. The quantity of product lost varies depending on the part of the car that is damaged in an accident; consequently, use of release risk can affect how different modifications in tank car design are considered. The metric was developed in terms of tank-damage-caused and non-tank-damage-caused releases. It was found that tank-damage-caused releases had a higher release risk than non-tank-damage-caused releases. Important elements considered are the probabilities of release and the expected quantities of release from the tank components and non-tank components of a tank car, and the effect of increasing tank thickness in increasing accident exposure and decreasing expected quantity of release. The release risk metric is also used as the objective function in a tank thickness optimization model. The results suggest that release risk may be a useful means of assessing the relative benefits of different tank car safety design modifications.

Texte intégralRésumé :
In this paper, the author investigates the use of the popular Social Networking Site (SNS) Facebook to solve crimes. In particular, the author uses car thefts as a case study. When a car owner discovers that his or her vehicle has been stolen, every means helps to recover the vehicle. Reporting the incident immediately to the police is obligatory, but alerting his or her network of friends on a social networking site about the misfortune could prove useful. In particular, the authors look into a real case study. This report answers several questions, such as: How useful can these sites be to help an owner recover the vehicle? How far can an appeal reach? What type of feedback do users send? The author analyzes how people create the appeal in Facebook and what information is shared.

Texte intégralRésumé :
Travellers’ discourses thrive on anecdotes. According to Stephen Greenblatt, they interpose between a series of similar, narrow experiences and a wider pattern they may indicate. This analysis deciphers how an anecdote from Passenger to Teheran (1926), the travelogue written by Vita Sackville-West, is not just an isolated flash but can indicate larger representational strategies. In her epic journey Vita Sackville-West travelled from London to Egypt, India, Persia, and then back to England, through Russia, Poland and Prussia; by boat, train and car. In the episode which is subject to a detailed analysis, the travellers were stopped at the Polish–East Prussian border and forced to leave the train. The consequences of what could be just an anecdote about an “unwelcome incident”, reverberate – as it turns out – far beyond the incidental because what is at stake at almost every border incident is a socio–political, geo–political, military and ideological reality. No matter whether such events are presented as adventures or in all seriousness, each border trouble has consequences beyond any “local moment”. To disclose some of the less obvious implications of the Polish–Prussian passage in Vita Sackville-West’s book is the aim of this essay.

Texte intégralRésumé :
On Friday, 30 August 1918, the day M. S. Uritskii, chairman of the Petrograd Cheka, was assassinated, Lenin was scheduled to address the Corn Exchange in the Basmannyi district of Moscow at 6:00 P.M. and the Mikhelson Armaments Factory in the Serpukhovskii section later. The first speech passed without incident; at the Mikhelson factory he gave the same fifteen-to-twenty minute speech he had delivered at the Corn Exchange, an attack on the forces of counterrevolution. In both locations he concluded his speech with the words “there is only one issue, victory or death!” As Lenin returned to his car in the factory courtyard, three shots were fired and he fell to the ground with bullet wounds in his left shoulder and the left side of his neck; the third bullet hit a woman standing nearby. The workers accompanying him to his car ran off, crying, “they've killed him, they've killed him!” and the crowded courtyard emptied quickly.

Texte intégralRésumé :
Roll on-roll off (Ro-Ro) ship is the preferable vessel for public transportation and also as a medium to distribute several commodities. Its operations are a straightforward process but traffic management is quite delicate, especially for cross-route. Moreover, maritime incidents sometimes occur, causing significant casualties and in the case of the Ro-Ro, collision with other ship is a possible threat with the ability to trigger immense damages. This research, therefore, was conducted to assess the structural casualties of a Ro-Ro vessel under collision. This was modelled with respect to a ship involved in a certain incident in Indonesia in the latest decade, and the designed collision problems were calculated using the finite element approach. The collision angle was selected as the main input parameter with the straight collision of angle 90° and oblique collision with different angles applied to the scenario. The results found the collision energy due to structural destruction to have distinct pattern and peak value under oblique cases with lower values observed for straight collision for all scenarios. It is, however, recommended that energy should be taken as an initial parameter in further investigation of structural damage and response contour.

Texte intégralRésumé :
The following elaboration has two purposes. One is to invite further reflections on the recent incident of the German sports car manufacturer, Porsche, revealing its until-then unknown substantive holdings in Volkswagen, its much larger competitor. The Porsche incident provoked a host of reactions, ranging from satisfaction to outrage to consternation. The essay's second purpose is to stimulate considerations about likely policy responses and their implications. While the remarkable Porsche incident illustrates the particular nature of the embeddedness of global financial markets, meaning that while investors can inject and pull out of nationally located business opportunities in a seemingly uninhibited fashion, this activity is nevertheless occurring within a complex regulatory setting. As this intervention shows, such transnational settings often require sophisticated regulatory structures and responses. But it is crucial to ensure that – especially in times as the current financial crisis – no excessive accumulation of regulatory actions occurs. Consequently, blind regulatory spots as the ones revealed in this paper will ultimately occur. Nevertheless, it is important that market participants and potential investors are aware of them because then it those blind spots can be used efficiently.

Texte intégralRésumé :
An anti-lock braking system (ABS) is a basic skid control system that can prevent the tire from locking up. In an emergency braking situation, a high possibility that the skidding phenomenon can occur without ABS. This incident become worse when an emergency braking is applied either on wet or dry surfaces. Although ABS is crucial to prevent the collision, some vehicles still do not have ABS. This study is aimed to analyse the vehicle’s dynamic behaviour during emergency braking on wet and dry surface condition. The experimental vehicle model is a Malaysian sedan car namely Proton Persona. This instrumented car is equipped with sensors,video camera and data acquisition systems to determine the vehicle’s motion. In the experiment,when the vehicle reached a maximum speed of 60 km/h, the driver push the brake pedal firmly until the car stop. From the experimental results, the effect of emergency braking without ABS is clearly seen at the wheel speed. The tire locked up can be observed when emergency braking was applied on the wet surface. However, for the emergency braking on the dry surface, the tire decreased gradually. This finding shows that without ABS, the vehicle is unsafe and accident can occur. The experimental data from this study also can be used as a guideline to a researcher and manufacturer in the development of ABS and safety system of the vehicle

The TravTek system constitutes a major Intelligent Vehicle-Highway System (IVHS) Advanced Traveler Information System (ATIS) demonstration project. The system provided in-vehicle information via color touchscreen CRT, steering wheel buttons, and synthesized voice. The TravTek driver interface was developed with the intent of providing navigation, service and attractions, and roadway incident and traffic information to the driver. The design of the TravTek interface had as its primary objectives: (1) more effective driver navigation providing the benefit of saving time, (2) easy access to valuable and convenient location information to alleviate stress and increase driving enjoyment, (3) maintenance of safe driving performance during system use and safety improvement facilitated by information for avoiding hazards and for emergency response, and (4) improvement of roadway efficiency to alleviate congestion. This paper provides detailed data regarding driver performance and behavioral interactions with four TravTek navigation configurations and two conventional methods of navigation: a paper map and a textual direction list. The results indicate that turn-by-turn information, regardless of its method of presentation, results in effective driving and navigation performance. A moving map display with no supplemental information required high visual attention relative to the other conditions. The other TravTek conditions resulted in lower workload superior navigation performance than the paper map control condition.

Texte intégralRésumé :
Abstract Humans recognize objects visually on the basis of material composition as well as shape. To acquire a certain level of photorealism, it is necessary to analyze, how the materials scatter the incident light. The key quantity for expressing the directional optical effect of materials on the incident radiance is the bidirectional reflectance distribution function (BRDF). Our work is devoted to the BRDF measurements, in order to render the synthetic images, mostly of the metallic paints. We measured the spectral reflectance off multiple paint samples then used the measured data to fit the analytical BRDF model, in order to acquire its parameters. In this paper we describe the methodology of the image synthesis from measured data. Materials such as the metallic paints exhibit a sparkling effect caused by the metallic particles scattered within the paint volume. Our analysis of sparkling effect is based on the processing of the multiple photographs. Results of analysis and the measurements were incorporated into the rendering process of car paint

Texte intégralRésumé :
Evidence must be presented neatly and with care to solve forensic cases because the ability to resolve legal cases depends only on the availability of appropriate evidence. Evidence is used to uncover connections between the victim, the place and time of the incident, and the perpetrator in order to resolve the incident. One of the most important types of evidence examined in forensic investigations is textile materials. Because everyone who commits a crime or is a victim of crime is in contact with textile surfaces. Textile products such as clothing, furniture, knife marks on fabric, blood on car upholstery, vehicle upholstery found at the crime scene can be used as evidence to help solve the crime. During forensic examination, fibers can be classified according to certain criteria such as colour, shape, surface texture, thickness, fluorescent properties, and chemical composition. As a result of examining these classifications, the case can be clarified as quickly as possible. Otherwise, finding the perpetrator may become more difficult as time goes on.

Texte intégralRésumé :
Commercial floating car data (FCD) is being increasingly used as a traffic data source due to its lower cost despite concerns about its reliability. This paper focuses on the evaluation of FCD speed quality as a surrogate measure for arterial speed from different aspects. First, FCD speed is compared to video-based traffic data, collected from a specific urban road segment and assumed as ground truth in (a) descriptive evaluations, (b) speed estimation, and (c) level of service estimation. Regression analysis carried out to derive transformation function between two datasets showed a nonlinear relation with a high correlation coefficient of 0.82. Working with data along an urban corridor of 3.6 km also showed that despite some outliers, FCD was capable of detecting peak-hour queue formations as well as incident related ones. Use of transformation function on FCD speeds helped to increase its potential in urban traffic monitoring.

Blood 136, Supplement 1 (5 novembre 2020) : 7. http://dx.doi.org/10.1182/blood-2020-136782.
Texte intégralRésumé :
Introduction: Chimeric antigen receptor modified T Cell (CAR-T) therapy is a rapidly developing treatment for patients with relapsed/refractory (R/R) B-cell non-Hodgkin lymphoma (NHL) or multiple myeloma (MM). Although this population is at high risk for thrombosis, there are few data about rates of venous thromboembolism (VTE) and arterial thromboembolism (ATE) with CAR-T. Additionally, treatment with anticoagulation is complicated because of the prevalence of thrombocytopenia following CAR-T. Our goal was to determine the incidence, associated risk factors, management and outcomes of VTE and ATE in the 60 days following CAR-T therapy. Methods: We performed a single-center, retrospective cohort study of all patients who received inpatient CAR-T cells at UCSF Medical Center between January 2018 and May 2020 for R/R NHL or MM as standard-of-care or on a clinical trial. The outcomes of incident VTE and ATE were identified by ICD-10 codes and medical record review. Patient characteristics, pre-existing thrombosis risk factors, laboratory results, medications, and major or clinically relevant non-major bleeding or recurrent thrombotic complications were obtained through chart review. We used descriptive statistics to delineate risk factors, incidence, management and outcomes of thrombotic events. Results: Ninety-one patients who underwent CAR-T therapy were included in the analysis, 37 with NHL and 54 with MM. For NHL, mean age was 63 (range 38-82), and 41% were women. For MM, mean age was 62 (range 33-77), and 50% were women. Patients with NHL were treated with either investigational or Federal Drug Administration-approved CD19-directed therapies, and patients with MM were treated with a variety of investigational B-cell maturation antigen-directed (BCMA) therapies. For thrombotic risk factors, 13% of patients with NHL had a history of VTE, 3% had a history of ATE, 27% had a BMI ≥30, 59% had a recent procedure including central venous catheter (CVC) placement, 14% had an intensive care unit (ICU) stay, and 22% had an infectious complication in the 30 days pre- or post-CAR-T. Forty-one percent of patients with NHL had neurotoxicity of any grade, and 59% had CRS of any grade. At 30 days, 57% had a complete response, 41% had a partial response, 3% had stable disease. For MM, 6% of patients had a pre-existing history of VTE, 2% had a history of ATE, 19% had a BMI ≥30, 96% had a recent procedure, 11% had an ICU stay and 19% had an infection. Seventeen percent had neurotoxicity, and 85% had CRS. Thirty-two percent of patients with NHL and 48% with MM received pharmacologic VTE prophylaxis while undergoing CAR-T. For those who did not receive VTE prophylaxis, thrombocytopenia was the reason for holding prophylaxis, which occurred in 51% and 50% of NHL and MM patients, respectively. In the 60 days post-CAR-T, 4 (11%) patients with NHL were diagnosed with VTE-3 pulmonary embolism (PE) and 1 lower extremity deep vein thrombosis (DVT) associated with a previously placed inferior vena cava filter. Four (7%) patients with MM were diagnosed with VTE-1 PE and 3 upper extremity DVTs associated with CVCs. Five out of these 8 (63%) patients had symptomatic VTE, while the remainder were incidental on PETCT. Mean time from CAR-T infusion to VTE diagnosis was 20 days (range 6-39 days). There were no documented ATEs. Six out of 8 (75%) were treated with therapeutic anticoagulation. Of those who were anticoagulated, 4 patients received direct oral anticoagulants and 2 received low-molecular-weight-heparin. Duration was 3 months in 3 patients, 11 days in 1, 150 days in 1, and indefinitely in 1 with atrial fibrillation. Among all 8 patients with VTE, there were no bleeding events or recurrent thromboses regardless of whether or not they received anticoagulation. Discussion: In this cohort of patients with R/R NHL or MM who received either CD19- or BCMA-directed therapies, almost 1 in 10 developed VTE in the 60 days post-CAR-T. This occurred in the context of a high prevalence of risk factors for thrombosis and low rates of pharmacologic prophylaxis. Among those who developed VTE, the majority were treated with therapeutic anticoagulation for at least 3 months, without documented bleeding or recurrent VTE. Our findings provide crucial information on a common complication that can inform patients, clinicians and researchers and should be expanded upon in larger, prospective studies to identify optimal preventive and therapeutic strategies.

Texte intégralRésumé :
The automotive industry has been transformed through technological progress during the past decade. Vehicles are equipped with multiple computing devices that offer safety, driving assistance, or multimedia services. Despite these advancements, when an incident occurs, such as a car crash, the involved parties often do not take advantage of the technological capabilities of modern vehicles and attempt to assign liability for the incident to a specific vehicle based upon witness statements. In this paper, we propose a secure, decentralized, blockchain-based platform that can be employed to store encrypted position and velocity values for vehicles in a smart city environment. Such data can be decrypted when the need arises, either through the vehicle driver’s consent or through the consensus of different authorities. The proposed platform also offers an automated way to resolve disputes between involved parties. A simulation has been conducted upon a mobility traffic dataset for a typical day in the city of Cologne to assess the applicability of the proposed methodology to real-world scenarios and the infrastructure requirements that such an application would have.

In this paper, we proposed an image processing technique for automatic real time fire and smoke detection in tunnel environment. To avoid the large scale of damage of fire occurring in the tunnel, it is necessary to have a system to sense and minimize the incident as fast as possible. However it is impossible for human observation of Closed-Circuit Television (CCTV) in tunnel for 24 h. So if the fire and smoke detection system through image processing can warn a fire, it will be very convenient, and it can be possible to minimize damage even when no one is in front of the monitor. The fire and smoke detection is different from forest fire detection as there are elements such as car and tunnel lights and others that are different from the forest environment so an indigenous algorithm has to be developed. The two algorithms proposed in this paper are able to detect the exact position at the earlier stage of incident. In addition, by comparing properties of each algorithm throughout experiment, we have proved the validity and efficiency of proposed algorithm.

Texte intégralRésumé :
This paper presents the design of a virtual reality learning module inspired by the exercises of healthcare professionals and its limitations as a result of action research carried out by the authors’ collective. The module is implemented on a car crash scenario as a emergency event. Virtual reality training is presented here as an important supplement to traditional paramedic training with the potential to reduce costs and make paramedic training more effective as part of their refresher training for their job roles. Real-time training and its limitations are described, especially regarding patient triage, this aspect being considered as one of the key aspects in the context of virtual reality. Furthermore, the results of a questionnaire survey among the mannequins and interviews with the trainees are presented, while the virtual reality environment of the module was designed to be intuitive for each student with the possibility of self-service without major demands on the logistical organization of the staff for the updating training. The authors relied on an expert group of multi-disciplinary experts for development. The outcome of the action research and the data collected by it is a fully prepared module for teaching selected skills in reflection of the situational context of a traffic accident with mass casualties. In the context of the presented module, measurements are being prepared to compare selected variables between real training and virtual reality training with the same scenario on student paramedics and professional paramedics.

Texte intégralRésumé :
High-speed trains have a sustained high-noise level for long periods during operation. Although such high-noise levels are effective for acoustic energy harvesting, a practical design for an acoustic energy harvesting system from a high-speed train is lacking. In this study, the design of an energy harvesting system was implemented utilizing noise from a high-speed train during practical operation. We investigated the noise generated from a high-speed train and derived the characteristics of the main noise sources. The results confirmed that low-frequency noise of 50–200 Hz was generated in the passenger, cab, and between car sections. Results from this investigation were used to design a Helmholtz resonator for a target noise of 174 Hz based on a theoretical model. Moreover, numerical simulation was conducted using sound source speakers to investigate vibrations in the walls of the resonator. Finally, energy harvesting experiments were conducted using various types of piezoelectric elements such as rectangular and circular plates. Experimental results indicate that approximately 0.7 V was generated for an incident sound pressure level of 100 dB using a large rectangular plate. Such power level is sufficient to power a variety of low-power electric devices.

AbstractIntroductionDuring mass-casualty incidents (MCIs), patient volume often overwhelms available Emergency Medical Services (EMS) personnel. First responders are expected to triage, treat, and transport patients in a timely fashion. If other responders could triage accurately, prehospital EMS resources could be focused more directly on patients that require immediate medical attention and transport.HypothesisTriage accuracy, error patterns, and time to triage completion are similar between second-year primary care paramedic (PCP) and fire science (FS) students participating in a simulated MCI using the Sort, Assess, Life-saving interventions, Treatment/Transport (SALT) triage algorithm.MethodsAll students in the second-year PCP program and FS program at two separate community colleges were invited to participate in this study. Immediately following a 30-minute didactic session on SALT, participants were given a standardized briefing and asked to triage an eight-victim, mock MCI using SALT. The scenario consisted of a four-car motor vehicle collision with each victim portrayed by volunteer actors given appropriate moulage and symptom coaching for their pattern of injury. The total number and acuity of victims were unknown to participants prior to arrival to the mock scenario.ResultsThirty-eight PCP and 29 FS students completed the simulation. Overall triage accuracy was 79.9% for PCP and 72.0% for FS (∆ 7.9%; 95% CI, 1.2-14.7) students. No significant difference was found between the groups regarding types of triage errors. Over-triage, under-triage, and critical errors occurred in 10.2%, 7.6%, and 2.3% of PCP triage assignments, respectively. Fire science students had a similar pattern with 15.2% over-triaged, 8.7% under-triaged, and 4.3% critical errors. The median [IQR] time to triage completion for PCPs and FSs were 142.1 [52.6] seconds and 159.0 [40.5] seconds, respectively (P=.19; Mann-Whitney Test).ConclusionsPrimary care paramedics performed MCI triage more accurately than FS students after brief SALT training, but no difference was found regarding types of error or time to triage completion. The clinical importance of this difference in triage accuracy likely is minimal, suggesting that fire services personnel could be considered for MCI triage depending on the availability of prehospital medical resources and appropriate training.LeeCWC, McLeodSL, Van AarsenK, KlingelM, FrancJM, PeddleMB.

Texte intégralRésumé :
Background: There has been a significant increase in the number of train crashes worldwide, mainly due to the extension of the rail network and the use of the most sophisticated and cutting-edge technology. Incident Report: The Tehran-Zahedan train had 260 passengers on board and left for Tehran City at 14:50 local time on Wednesday, September 25, 2019. The accident happened at 16:20 local time at 100 km distance from Zahedan City. Results: Five train cars derailed 2 km from Shorou Station, where four people died, and 157 were injured. According to the investigations, the accident occurred due to the unscrewing of some bolts and spring washers. There were 170-180 screws and spring washers removed along 50-60 m, which resulted in the creation of a dangerous point and derailment of the train. This study examined the challenges, strengths, and learned lessons of the incident. Conclusion: Concerning standard and vast rail networks in Iran and the latest train crashes that mainly occurred just outside the cities, accessibility to the accident scene should be considered one of the most important physical vulnerability indexes. As a result, accessibility to special firefighting and rail rescue train car at some stations in crowded routes effectively decreases the consequences of such accidents.
